ToaZZ whom t mcyooncem Be it known that L'Anonro on CLAinifroN'r, citizen: of the United States, residing at y Toledo, in the county of Lucas and State of Ohio, haveinvented certain new and useful Improvements in Transmission-Locks for v Motor-Vehicles, of'which the `following isa specification.

invention relates Vto an improved transmission lockA for motor vehicles and has as one of its principal objectsto provide 'l a device of this characterwhich will be characterized by structural simplicity and which will7 at the same time, effectually prevent unautorized use of` a vehicle equipped therewit.""` V f A furtherobject of the invention is to provide a device whereinthe shank of the transmission controllever `above ther ball joint thereof may not only be removed but wherein means will be provided for preventing access to said joint so as to avoid engagement of a substitute lever with thejoint fmt shifting the gears.

' And the invention has as a still'A furtherV object to provide a `device ywhich maybe readily Aemployed in' connection with substantially any conventional vdesign of transmission gear as now in-common use. j

Other 'and incidental objects will appear hereinafter;`

F ig. 5 is a detail showing a further slight modification. i i

Referring now more particularly to the drawings, I have shown my improved lock in connection with a motor vehicle gear set of conventional design. However, since the gears themselves do not concern the present invention, they have not been illustrated.

The case of the gear set is indicated at 10- and projecting upwardly from said case is the usual socket 11 in which is mounted a Specification of Letters Patent., ,j Pittnled NOV. 2951921.; Application vfiled September 21, 1920. Serial No. 411,8v00. y i

ball 12 providing 'aj oint for the control lever employed. Below the joint the lever is 1 formed. in the customary manner whereby the lever may `be'manipulated for shifting the gears. `is 1s usuahthe socket jll extends f upwardly through the iioor 13'of the vehicle.

In carrying `the invention into y eect, form uponthe ball l2 an upstanding tubularl socket 14C provided in its wall with a bayonety slot l5 and removably 'engageable at itsv lower endvin said socket is a lever shankV 16.'V

At its upper end this shank is provided with the usual ball 17 while upon the lower end ofthe shankis formed a lug 18 engageable in the slot-l5l of the socket. Consequently,

\ as will be appreciated, the shank maybe inserted in the socketand locked therein when, of course, the' shank of the lever maybe manipulated' for shifting the transmission gears. lliountedupon the floor 13v of the vehicle `to overliethe ball joint of the lever through which are engaged boltsjorr other approved' fastening devices 2,2 extending through the floor 13 for permanently securey ing the casing thereto. .Formed in the top wall 20 of the casing is an oblong door opening`23 disposed above the ball l2vand se cured within the casing at one side 4of said opening is ay loclr2llf.` This lock may be of any approved type and is `preferably provided witha barrel 25 extending up through the topwall of the casing so thata key may bereadily inserted in the lock for actuating said lock. Secured to the lower face of the top wall20 of the casing at opposite ends of the door opening 23 are, as particularly shown in'F ig. '8, parallel 'cleats 26 and slidably supported by said cleats immediately Y beneath said wall is a substantially 1"-shaped door 27. Projecting from the forward edge of the door are'spaced catchbolts 28 adapted to ooact with the lock 24 and extending fromV y the rear edge of the door-medially thereof is a rearwardlydirected extension orarm 29105 projecting freely through the adjacent side wall of the casing. Suitably secured at their forward ends to the rear edge of the door at opposite sides of said extension are contractile springs 30, the opposite ends of which are appropriately fastened to the adjacent side wall of the casing so that said shifting the speed gears. On the other hand,

Y springs will normally act to hold the door v open lying at one side of the door opening 23.,

However, as willlbe appreeia'itechby pushing upon the extension 29 the doorrmaybe Y readily shifted toclosed*position-when the catch boltsY 28 will ride into the lock to beV engaged thereby so that the door willbe secured closed.

As will now be view oi4 the lpreceding description, when it is' desired to operate the vehicle,a key may l lbe inserted in the lock 24l ancl-thedooi' 27 released sov thatthe lever shank `16 may be Y engaged in the socket le ofthe ball 12.

The lever may then be freely moved for on leaving the vehicle, Ithe operator ,may

i"detach the lever shank 16 andV closeY the door, Ycarrying the4 ylever .shank away. Access tothe ball i2 of the leverwill then be prevented. However, even i should the door be broken open o r ythe casing-19 displaced, a person intendingto steal the vehicle would l i [still be vwithoutpractical means to engage inthe Socketvlejwhereby Ashitting ,ofthe gears might be effected.v lraccordingly pro# videa very eiiicient lock and, as Ylwill, now
